Question

Avani wrote the linear equation Y=5X+4. Then, she wrote the equation of the line that is perpendicular to Y=5X+4 and that passes through (15,–2). If her new equation is in the form Y=-1/5X+B, what is the value of b?

Answer 1

the answer is B= 1

Explanation:

hope it helps :)

Answer 2

The equation of the line perpendicular to Y = 5X + 4 is given by:
Y = -1 / 5X + B.
We observe that this line passes through the point (15, -2).
We have then:
-2 = -1 / 5 (15) + B.
Clearing B we have:
-2 = -3 + B.
-2 + 3 = B
B = 1
Answer:
the value of B is:
B = 1
